Most portfolio apps are built for one market, one broker, one currency. The moment your account list crosses a border — a US brokerage here, a European ISA there, an LSE-listed ETF on the side — they fall apart.
We built FolioLens because we lived this problem. Spreadsheets that lied about returns. Apps that ignored ISIN-listed UCITS ETFs. Dashboards that priced GBP holdings in USD without telling us.
FolioLens speaks ticker, ISIN, native currency and time-weighted return. It works across Trading 212, Interactive Brokers, Revolut, eToro and any broker that exports a CSV — and it shows you the truth in whichever currency you actually live in.
